  2. 1. Low Cycle Fatigue and Thermo-Mechanical Fatigue of Uncoated and Coated Nickel-Base Superalloys

    Author : Svjetlana Stekovic; Torsten Ericsson; Hael Mughrabi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AMDRY997; CMSX-4; SCB; Thermo-Mechanical Fatigue; Coatings; Gas Turbine; IC1; IC3; IN792; Low Cycle Fatigue; Nickel-Base Superalloys; RT22; Materials science; Teknisk materialvetenskap;

    Abstract : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. In such environments superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface. READ MORE

  4. 2. Machinability variations in Alloy 718 —With focus on machining of turbine components

    Author : Pajazit Avdovic; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

    Abstract : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). READ MORE

  5. 3. Thermal and Mechanical Behaviors of High Temperature Coatings

    Author : Kang Yuan; Lin Peng Ru; Xin-Hai Li; Sten Johansson; Yan-dong Wang; Nicolaie Markocsan; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With superior oxidation and corrosion resistance, metallic coatings (i.e. diffusion coatings and MCrAlX coatings) are widely used to protect hot components made of superalloys in turbine engines. READ MORE

  6. 4. Performance of High-temperature Coatings : Oxidation and Interdiffusion

    Author : Xiaoyu Sun; Ru Lin Peng; Johan Moverare; Xin-Hai Li; Lindwall Greta; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; diffusion; phase transformation; oxidation;

    Abstract : The use of aluminiferous coatings profoundly improves the service life of superalloys but leads to the microstructural degradation of superalloys and thus the loss of mechanical properties. To solve this trade-off, two strategies were employed in this research. READ MORE

  7. 5. Isothermal low cycle fatigue of uncoated and coated nickel-base superalloys

    Author : Svjetlana Stekovic; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. However, the superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface of the superalloys. READ MORE
